Follow basic safety precautions when using your smart air fryer toaster oven.
Read all instructions.
IMPORTANT SAFEGUARDS
Key Safety Points
General Safety
• Do not touch hot surfaces. Use
handle.
• The outside of the oven, including
the door, is hot during and after use.
• Always use heat-resistant gloves,
pads, or oven mitts when handling
hot materials, and when placing
items in or removing items from
the oven, including trays, racks,
accessories, or containers.
• When the oven is not in use, and
before cleaning, press and hold the
TIME/SHADE for 3 seconds to turn
o the display, then unplug from
outlet. Allow to cool completely
before putting on or taking o parts.
• Do not immerse the housing, cord,
or plug in water or liquid.
• Close supervision is necessary when
the oven is used by or near children.
• Children should be supervised to
ensure that they do not play with the
oven.
• Do not use your oven if it is
damaged, not working, or if the
cord or plug is damaged. Contact
Customer Support (see page 33).
• Do not use third-party replacement
parts or accessories, as this may
cause injuries.
• Do not use outdoors.
• Do not place the oven or any of its
parts on a stove, near gas or electric
burners, or inside another heated
oven.
• Be extremely cautious when
removing a tray, basket, or rack if it
contains hot oil, grease, or other hot
liquids.
• Do not clean with metal scouring
pads. Metal fragments can break o
the pad and touch electrical parts,
creating a risk of electric shock.
• Clean the crumb tray after using.
Accumulated grease and crumbs can
overheat and catch fire.
• Do not store anything on top of
your oven while it is operating.
Do not store anything inside your
oven other than recommended
accessories.
• The oven is not intended to be
operated by means of an external
timer or separate remote-control
system.
• Only use as directed in this manual.
Do not use oven for any purpose
other than its intended use.
READ AND SAVE THESE
INSTRUCTIONS

EN
• To avoid risk of fire or electric
shock, do not place oversized foods
or metal utensils (except ocial
COSORI accessories) into the oven.
• Do not place paper, cardboard, or
non-heat-resistant plastic into your
oven, or any materials which may
catch fire or melt.
• To avoid overheating, do not use
metal foil in the oven unless directed.
Use extreme caution when using
foil, and always fit foil as securely
as possible. If the foil contacts the
oven’s heating elements, this can
cause overheating and risk of fire.
Do not cover crumb tray or any part
of the oven,except for the Food Trays
or Racks as directed, with metal foil.
• Never put baking or parchment
paper into the oven without food on
top. Air circulation can cause paper
to move and touch heating elements.
• Always use heat-safe containers.
Be extremely cautious if using
containers that aren’t metal or glass.
• Keep your oven away from
flammable materials (curtains,
tablecloths, walls, etc.). Use on a flat,
stable, heat-resistant surface away
from heat sources or liquids.
• Immediately turn o and unplug
your oven if you see dark smoke
coming out. Food is burning. Wait for
smoke to clear before opening the
oven door.
While Cooking
Note: See Care & Maintenance
for instructions on how to clean
accessories (page 28).
CAUTION: Hot surface
Caution: 60 minutes “ON” in a 2-hour
period.
Note: The heating elements do not
exceed 60 minutes “on” in a 2-hour
period to maintain the set temperature.
• This oven is not intended for use by
persons (including children) with
reduced physical, sensory, or mental
capabilities, or lack of experience and
knowledge, unless they have been
given supervision or instruction
concerning use of the oven by a
person responsible for their safety.
• Do not allow children to clean or
perform maintenance on the oven.
• Keep the oven and its cord out of
reach of children.
• To turn the oven o, press and hold
TIME/SHADE for 3 seconds to turn
o the oven.
• We recommend allowing a few
inches of space for the toaster oven
to vent. Do not cover the air intake
vents or air outlet vents while unit is
operating. Doing so will prevent even
cooking and may damage the unit or
cause it to overheat.
• Not for commercial use.
Household use only.

EN
• This oven uses a short power-supply
cord to reduce the risk of entangling
or tripping.
• Your oven has a polarized plug (one
prong is wider than the other), which
fits into a polarized outlet only one
way. If the plug does not fit, reverse
the plug. If it still does not fit, do not
use the plug in that outlet. Do not
alter the plug in any way.
• Do not let the power cord (or any
extension cord) hang over the edge
of a table or counter, or touch hot
surfaces.
• The cord should be arranged so that
it will not drape over the countertop
or tabletop where it can be pulled
on by children or tripped over
unintentionally.
• If the power supply cord is damaged,
it must be replaced by Arovast
Corporation or similarly qualified
persons in order to avoid an electric
or fire hazard. Please contact
Customer Support (page 33).
Power & Cord Extension Cords
Electromagnetic Fields (EMF)
• Longer extension cords are available
and may be used if care is exercised
in their use.
• If a longer extension cord is used:
• The marked electrical rating of the
cord set or extension cord should
be at least as great as the electrical
rating of the oven.
• The cord should be arranged
so that it will not drape over the
countertop or tabletop where it
can be pulled on by children or
tripped over unintentionally.
• The cord should be a grounding-
type 3-wire cord.
This oven complies with all standards
regarding electromagnetic fields (EMF).
If handled properly and according to
the instructions in this user manual,
the appliance is safe to use based on
scientific evidence available today.
